Delhivery — Shipment Not at all Delivered

This is one of the super annoying delivery company where you don't konw what's happening with your shipment, for my order they are just updating the status round and round, even shipment reached to destination they haven't delivered, and updating the status retroactively, No contact number even if you send and email you can't expect response soon, they don't even contact you. It has been almost a month now, but shipment not delivered, and automatic mail says shipment cancelled instead
